Marjorie Henry, Contributor
How
well did you do on the multiple-choice
items given in the last lesson? They
were all testing you on greenhouse
gases.
If
you had attempted them, and I trust
you did, check your answers below.
Should you give an incorrect answer,
my advice is to review the relevant
topic.

- D; 2 - A; 3 - B; 4 - B; 5 - A; 6
- C; 7 - C; 8 - D; 9 - A; 10 - B
